I've recently published The Hospitality Girl using KDP.
The story concept began as a recollection of one of my former patients. She needed a listening ear, I allowed her the chance to tell her story.
She called herself a hospitality girl. She was available to escort visitors, including some notables, around Chattanooga and the surrounding area. It is a similar concept to what is employed on college campuses across America today. Today, when an athlete visits a college, a pretty girl or handsome guy, cheerleader or otherwise, is there to give them a tour and help them get a feel for what the university has to offer. It was the same with my patient as a young woman. She was an escort, with the hopes of convincing dignitaries/convention reps/etc. that Chattanooga had a lot to offer.
The portion of the storyline that takes place in Hollywood is fictional, imagined as a possible reality for a young woman in 1954 Hollywood. It was written long before the revelations regarding Harvey Weinstein and others, but was conjectured as a possible reality. That the fictional storyline may mirror some young woman's reality during that, or any other time period, is a sad statement on some inequities in our society.
Storyline opportunities arise daily. They borrow their existence from the people around us. It is up to the writer to develop the ability to listen and convey what we've heard to an interested audience.
I hope today reveals a good storyline. I hope you as a listener, and those to whom you lend an ear, both benefit from a moment shared.
Good luck, and, whatever else you do, keep writing.
